But we already know that, for instance, oral biomes are built around social interaction. Some oral cultures are much more cariogenic, and the more secondhand oral bacteria you're exposed to, the greater the odds that you'll have a tooth-damaging oral biome, yourself.

If your parents had a lot of cavities while you were growing up, odds are you already contracted pernicious species, but the point is that we know that some kinds of microbiome dysfunction diseases are transmissible. Acne is another example.

Don't get me wrong. Keep working on this.

Shouldn't the oral biome be the easiest one to replace? I'd imagine regular rinsing with something antibacterial + regular introduction of the desired biome should do the trick. This of course assumes that it's not the conditions (aka diet etc.) that are mainly responsible for the biome. But if that was the case, the paper in OP also wouldn't make much sense
